.SH "DESCRIPTION"
.PP
The \fBstorescu\fP application implements a Service Class User (SCU) for the Storage Service Class\&. For each DICOM file on the command line it sends a C-STORE message to a Storage Service Class Provider (SCP) and waits for a response\&. The application can be used to transmit DICOM images and other DICOM composite objects\&.

peer        hostname of DICOM peer

.SS "Scanning Directories"
Adding directories as a parameter to the command line only makes sense if option \fI--scan-directories\fP is also given\&. If the files in the provided directories should be selected according to a specific name pattern (e\&.g\&. using wildcard matching), option \fI--scan-pattern\fP has to be used\&. Please note that this file pattern only applies to the files within the scanned directories, and, if any other patterns are specified on the command line outside the \fI--scan-pattern\fP option (e\&.g\&. in order to select further files), these do not apply to the specified directories\&.

The default behavior of \fBstorescu\fP is to propose two presentation contexts for each supported SOP class (abstract syntax) - one with the preferred transfer syntax and one with all other uncompressed transfer syntaxes\&. The default preferred transfer syntax is explicit VR with byte ordering corresponding to the local byte ordering of the machine on which \fBstorescu\fP is running\&. This behavior can be changed with the \fI--propose\fP, \fI--combine\fP and \fI--required\fP options, see above\&. Depending on these options, the following transfer syntaxes are supported:

Additional Storage SOP Classes and Transfer Syntaxes can be used with the so-called 'association negotiation profiles' (see below)\&.
.PP
The \fBstorescu\fP application does not support extended negotiation by default\&. However, using an appropriate association negotiation profile (see below) the optional support for extended negotiation can be added to particular SOP classes\&.
.SS "Association Negotiation Profiles and Configuration Files"
\fBstorescu\fP supports a flexible mechanism for specifying the DICOM network association negotiation behavior, based on so-called 'association
negotiation profiles' which may be read from a configuration file\&. The format and semantics of this configuration file are documented in \fIasconfig\&.txt\fP\&.
.SH "LOGGING"
.PP
The level of logging output of the various command line tools and underlying libraries can be specified by the user\&. By default, only errors and warnings are written to the standard error stream\&. Using option \fI--verbose\fP also informational messages like processing details are reported\&. Option \fI--debug\fP can be used to get more details on the internal activity, e\&.g\&. for debugging purposes\&. Other logging levels can be selected using option \fI--log-level\fP\&. In \fI--quiet\fP mode only fatal errors are reported\&. In such very severe error events, the application will usually terminate\&. For more details on the different logging levels, see documentation of module 'oflog'\&.
.PP
In case the logging output should be written to file (optionally with logfile rotation), to syslog (Unix) or the event log (Windows) option \fI--log-config\fP can be used\&. This configuration file also allows for directing only certain messages to a particular output stream and for filtering certain messages based on the module or application where they are generated\&. An example configuration file is provided in \fI<etcdir>/logger\&.cfg\fP\&.
.SH "COMMAND LINE"
.PP
All command line tools use the following notation for parameters: square brackets enclose optional values (0-1), three trailing dots indicate that multiple values are allowed (1-n), a combination of both means 0 to n values\&.
.PP
Command line options are distinguished from parameters by a leading '+' or '-' sign, respectively\&. Usually, order and position of command line options are arbitrary (i\&.e\&. they can appear anywhere)\&. However, if options are mutually exclusive the rightmost appearance is used\&. This behavior conforms to the standard evaluation rules of common Unix shells\&.
.PP
In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e\&.g\&. \fI@command\&.txt\fP)\&. Such a command argument is replaced by the content of the corresponding text file (multiple whitespaces are treated as a single separator unless they appear between two quotation marks) prior to any further evaluation\&. Please note that a command file cannot contain another command file\&. This simple but effective approach allows one to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file \fI<datadir>/dumppat\&.txt\fP)\&.
.SH "ENVIRONMENT"
.PP
The \fBstorescu\fP utility will attempt to load DICOM data dictionaries specified in the \fIDCMDICTPATH\fP environment variable\&. By default, i\&.e\&. if the \fIDCMDICTPATH\fP environment variable is not set, the file \fI<datadir>/dicom\&.dic\fP will be loaded unless the dictionary is built into the application (default for Windows)\&.
.PP
The default behavior should be preferred and the \fIDCMDICTPATH\fP environment variable only used when alternative data dictionaries are required\&. The \fIDCMDICTPATH\fP environment variable has the same format as the Unix shell \fIPATH\fP variable in that a colon (':') separates entries\&. On Windows systems, a semicolon (';') is used as a separator\&. The data dictionary code will attempt to load each file specified in the \fIDCMDICTPATH\fP environment variable\&. It is an error if no data dictionary can be loaded\&.
